To all t may concern:

Be it known that I, CHARLES F. HILLMAN, a citizen of the United States, residing at Wichita Falls, in the county of Wichita and 5 State of Texas, have invented new and useful Improvements in Oil-Refining Devices,

of which the following-is aspecification.

This invention relates to an oil refining apparatus and theprincipal object ofthe invention is to provide means for taking out the various operations of distillmg crude oil in one 'continuous operation and to Autilize the heat of the oil to effect the various changes necessary to separate the desired products from the crude oil, thus eiother features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, 11- lustrated in the accompanying drawings and 's ecilically pointed out in the appended c aim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a diagrammatic viewof one half ofA the apparatus. g

'Figure 1 is a like view of the other half. in these views 1 indicates a ipe still to e@ which theicrude oil is umped, y any suitable forni' of pump, t ough the piping Before reaching the -will the crude oil is passed through theheat exchangers 3 and 4 so that the oil in saidgpiping wi li be heated oils passing through an opposite directionfroliln he exchangers in K the oil passing through the piping 2.

` heated oii and vapors pass from thepipe still way of the pipe 6:' The vapors will pass from the dome 5 of to the separator .5' by the separator through the pi e 7 which conducts. the vapors throught e oiispipes of the ,cachan 4 so that' the heat freni .these vapors wilbe taken up by'v thefoil onits After' through the exchanger e the still, thus cooling the vapors.-..-.

vapors are led to the separator 8 which isV connected to the condenser 9 by the piping 10. The condensed oils inthe separator`8 iiow by gravity to the pipe line 11 to thel stills 12 and 13', for further distillation and the residues from these stills 12 and 13 areV withdrawn through pipeline 14.` After leading the ymaterial through the exchanger 3 it passes through the cooling box 15 and the extension 15 of this linev being connected with the pump. The unvaporized oil. from the separator 5 flows by ravity through pipe line 16 to stills 17 an 18 for further distillation, and the residue from these stills is withdrawn by the pipe line 19, which isv connected with the line 14 where bthe same passes into the exchanger 3. A by-pass 20 may connect the line 16 with the exchan er 'te y 3 vso as to cut out the stills 17 and 18. he stills 12 and 13 and 17 and 18 are connected by the vapor lines 21, 22, 23 and 24 to the condensers 25, 26, 27, and 28. The pumping out lines and the by-pass are provided with suitable valves .as atv 29 for closing these 'lines when desired. The condenser boxes are connected with the receiving house 30 in the well known manner.

` It will thus be seen that the various distilling operations are carried out in the one apparatus and in one continuous operation and by using the heated oils and lvapors to heat the incomin crude oil a great saving of fuel is eifecteld. The cold oil will also cool the vapor to condense fthe same and thus the minimum amount of water for coolin purposes is used.

n the exchan er 4 the crudeoil on its way` to the pipe still is heated by the vapors from the separator 5 so that said vaporsareA condensed ,and cooled 'before they reach the separator 8 and the uncondeiised vapors pass from the se arator 8 to the condenser 9. The remaining istillate discharges from the separator 8 to the stills 12 and 13 at a comparatively l'iigh temperature so that but a minimum amount of fuel is necessary to dstill the.' kerosene vapors in said stills, which passes to the condensers 25 and'26 by the linesf21 and 22.

l claim that my apparatus will produce gasoline, kerosene, gasoil, wax oil and fusi oil, in a esiitinuous operation and that the saving in hiel is' 42% and that 20% water is required for condensing purposes.;- that all re-running is eliminated, an

d all piirnping incident to charging re-run stills Aint - and proportioned to effect the desired results in each compartment of the apparatus.

It is thought from the foregoing descrip- 'tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with- -in the scope of the appended claim.

What I claim is e Anuapparatus of the class described comprising a pipe still, a pair of separators, a pipe line connecting the pipe still with one of said soparatrs, `a vapor pipe line conseparator with said stills so that the oil Will flow to said stills by. gravity, a pair of condensers connected with said pair of stills, a second pair of stills, a pipe line connecting the same with the first separator so that the oil will lflow into said stills by gravity, a pumping out line connected with the bottoms of said vpairs of stills, `valves in said discharging lines, the line leading' from the first separator With the pumping out line to cut out the second pair of stills, a valve in said by-pass and means for exchanging the heat of the oil in said pumping out line with the crude oil on its way to the pipe still.

In testimony whereof I afiix my signature.
